SPECILYFICATION forming part of Letters Patent No. 453,690, dated June9, 1891.

Application tiled September 6, 1890. Serial No. 364,156. (No model.)

T0 all when@ it Netty concern:

Beit known thatl, THoMAs Lewis CABLE- TON, a citizen ot the UnitedStates, residing at New Orleans, in the parish ot' Orleans and State ofLouisiana, have invented certain new and useful Improvements in RailwaySwitches; and I do declare the following to be a full, clear, and exactdescription ot' the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

Hy invention has relation toan improve-A ment in automaticrailway-switches; and it has for its object, among other things, toprovide a construction of switch whereby an engineer upon a moving trainis enabled to throw the point of the switch against the main trackwithout leaving his engine; and to the aecomplishment of this and otherends my invention consists in the construction, novel combination, andadaptation of the parts hereinafter described and claimed.

In the accompanying drz'twings,Figure 1 is a top plan view ot' myimprovements complete applied to an ordinary split switch, the saidswitch being in position for clear main track. Fig. 2 is a sideelevation of the leverlocking post, together with its component parts.Fig. 3 is a top plan viewof the switchoperating mechanism with the topor the guide-block removed and the switch set at main line. Fig. -t isaside elevation ofa portion of a locomotive carrying the trip foractuating my improvements. Fig. 5 is a top plan view ot' theswitch-operating mechanism adjusted to side track.7 Fig. G is a sideview of the trip removed from the locomotive, the same being shownelevated out of an operative position.

Referring by letter to the said drawings, A indicates the main line of arailway, and B a siding, while A indicate the split-switch railsdesigned to be operated by my improvements, as will be presentlydescribed.

Connected in a suitable manner to the under side of the switch -railsA', one of which forms a part of the main track and the other a part ofthe siding, is a transverse bar P, which is approximately of theproportional size shown, and is designed, in conjunction with the otherparts, to throw the point of the switch against the main track, as willbe presently described. Adjacent toits free end the bar P is providedwith a recess or guide a transverse of its length to reeeivea steppedbar S, which is adapted to move at right anangles to the bar P orlongitudinal of the track and to operate in conjunction with said bar P,as will be presently described.

R indicates a block or casing, in which the transverse bar P, thestepped bar S, and another transversely-disposed bar O, presently to bedescribed, are guided, said block or casing R being provided withguideways for the said bars, as illustrated. The bar O, which isprovided with a recess adjacent to its end to seat the enlarged portionof the stepped bar, moves in a guideway parallel to that of the bar P,and is connected adjacent to its other end with a vertically-disposedleverarm M, pivotally mounted at l) in the upright post T.

Connected at one end to the side and adjacent to the end of the slidebar P and having its other end sliding in a bearing connected to theimmovable rail of t-he main line is a bar Q, on which is mounted aspiral spring Q', which is of a resiliency suitable to the perttnmanceof functions presently to be set forth, and connected at one end to afixed disk on the rod, while its opposite end is attached to the bearingof said rod.

Connected to the upper side of Vthe stepped bar S and runninglongitudinally with respect to the track isa bar O,which is providedadjacent to the ends ot' said stepped bar with disks K to engage thestepped bar to move the same to operate the switch, as will behereinafter more fully specified. This bar C, which is of any suitablelength, is pivotally connected at its end to a short lever-arm II,carried at the end of a transverse rocking bar D, which is journaled ina suitable manner beneath the track at a suitable point in advance ot'the switch. Fixed adjacent to the end of said rocking bar D and upon theright-hand side of the track with respect to the direction of travel abeveled trip F, arranged to be engaged by a trip carried at the rightside of the locomotive. The trip U, which is pivotally mounted upon thelocomo- IOO tive adjacent to the track, may be of any pret'- erableconstruction, although that disclosed in the present embodiment of myinvention is preferable.

n practice the trip Uis designed to be connected with the cab of thelocomotive, so that the engineer may readily adjust the same t0 engageor pass over the trip F, as may be desired.

Moving in suitable guides formed in the post T adjacent to its upper endis a slidebar N, which moves in a direction parallel to the track, andis provided adjacent to its end with a notch or recess c to seat theupper end of lever M, for a purpose presently t0 be described. Pivotallyand loosely connected to one end et this bar N is a lever L, which isformed integral with or connected at its lower end to a rocking bar L',the opposite end of which is cranked and is connected in a suitablemanner adjacent to the enlarged end of the stepped bar S.

In operation the devices are normally in the positions shown in Figs. land 3 of the drawings, so as to presenta clear main track to anapproaching train. Now, if the engineer desires to run on the siding headjusts the trip U down, and said trip engages the trip or shoe F, whichmoves the bar C in the directionl indicated by the arrow and with saidbar moves the stepped bar S, which carries the reduced end of saidstepped bar into the recess of the bar P, when by the action of thespring Q upon the bar Q one of the split switch-rails will be thrownagainst one of the main-track rails, While the other will be thrown fromthe side-track rail, and thus present a siding to the approachingtrain.` The adjustment of the stepped bar S, as describen, will carrythe first or large step thereY of into the recess of the slide-bar O,and through the medium of the crank rocking bar L and lever L will movethe bar N so as to bring` the recess c into alignment with the lever M,and by this construction it will be seen that simultaneously with themovement of the stepped bar S by reason of the spring Q and bars P and Othe upper end of lever M will move toward the track and seat itself inthe notch c of the bar N. It will also be seenY that when the switch isset at main track the -bar N will lock the lever M and prevent it frommoving toward the track.

In practice it is obvious that signal-lights of suitable character mightbe placed upon the lever M, so as to notify the engineer whether theswitch is set at main or side track. It is further obvious that suchmodifications may be made in the form and general arrangement of theseveral parts as fairly fall within the scope of my invention.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

1. In a railway switch, the combination, with a switch-rail, of a blockarranged adjacent thereto and provided with guide-slots at right anglesto eachother, a transversely-disposed sliding bar connected to saidswitchrail and moving in one of the guides of said guide-block, aretracting-spring mounted on abar having one end connected to theslidebar and the other endconnected to one of the immovable track-rails,a stepped bar arranged at right angles to the transverse slidebar an d'adapted to engage a transverse recess therein,and abar connected to saidsteppedbar and arranged longitudinally of the track, said longitudinalbar carrying devices adapted to be engaged by a locomotive to adjust thesame longitudinally to move the switch, substantially as and forthepurpose specified.

2. In a railway switch, a switch rail, a guide-block arrangedr adjacentthereto, a sliding bar P, guided in said block and connected to saidswitch-rail` a bar connected at one end to said bar P and at its otherend to an im- -movable track-rail, a retracting-sprin g on said bar, astepped bar arranged at right angles to the bar P and adapted to engagea recess therein, a bar connected to said stepped bar and arrangedlongitudinally of the track and connected at its ends to devices adaptedto be engaged by a locomotive, in combination with a slide-bar moving inthe guide-block parallel t0 the bar Fand having a recess designed to beengaged by the stepped bar, the rocking barcranked at one end andconnected to the stepped bar, the lever connected at one end to saidrocking bar,a slide-bar guided in an upright post and having one endconnected to said lever, said bar being provided with a notch in itsside, and a lever connected to the slide-bar O adjacent to its end, alladapted to be operated substantially as and for the purpose specified.

In testimony whereof I afIiX my signature in presence of two witnesses.
